Regenerative medicine is newly developing science and technology, including tissue engineering, cell therapy, and gene therapy. The Japanese Society for Regenerative Medicine (JRSM), established in 2002, held the second annual meeting March 11–12, 2003 in Kobe. In the presidential address, Professor Tateishi underscored standardization of regenerative medicine. This meeting featured 401 general presentations including 179 posters and 222 platforms, 17 symposium/workshops including 101 papers, and 5 special lectures. As an important mission of this society to encourage investigators in this field, excellent paper awards were given to 34 people. This issue of Cell Transplantation contains 15 articles from the 34 awarded papers. Six articles highlight osteogenesis of stem cells. Wakitani et al. (13) demonstrated that the environment of osteochondral defect is chondrogenic for ES cells in rats. Takahashi et al. (11) reported that mesenchymal cells derived from the fetal part of the human placenta had an osteogenic potential, as shown by RT-PCR of several markers and deposition of calcium phosphate in vitro. The efficacy of osteogenesis of mesenchymal stem cells could be enhanced by the combination with platelet-rich plasma, as reported by Yamada et al. (15). Iida et al. (2) demonstrated that marrow mesenchymal cells could induce bone tissue when cultured with porous hydroxyapatite (HA), and the osteogenic capacity of the cultured bone/HA could be furthermore facilitated in vivo. Nishikawa et al. (9) examined the effect of pore size of HA on bone formation of marrow mesenchymal cells when cultured with HA in vitro, then implanted into the subcutaneous site. The results demonstrated that HA150 with 40 μm pore size was excellent compared with HA300 with 60–100 μm pore size. Kotobuki et al. (4) described a technique for isolation and enrichment of the cell population with high osteogenic capability from a human osteoblast line.

More about this publication?
Cell Transplantation publishes original, peer-reviewed research and review articles on the subject of cell transplantation and its application to human diseases. To ensure high-quality contributions from all areas of transplantation, separate section editors and editorial boards have been established. Articles deal with a wide range of topics including physiological, medical, preclinical, tissue engineering, and device-oriented aspects of transplantation of nervous system, endocrine, growth factor-secreting, bone marrow, epithelial, endothelial, and genetically engineered cells, among others. Basic clinical studies and immunological research papers are also featured. To provide complete coverage of this revolutionary field, Cell Transplantation will report on relevant technological advances, and ethical and regulatory considerations of cell transplants. Cell Transplantation is now an Open Access journal starting with volume 18 in 2009, and therefore there will be an inexpensive publication charge, which is dependent on the number of pages, in addition to the charge for color figures. This will allow work to be disseminated to a wider audience and also entitle the corresponding author to a free PDF, as well as prepublication of an unedited version of the manuscript.
